just tried to build glibc-2.13 "--with-cpu=440 --with-fp" on a Sam440ep[1]
(PPC440EP SoC [2]) but it remains stuck in this point:

Here my config.log: http://cruxppc.org/~acrux/config.log
Instead i successfully built glibc-2.13 without "--with-cpu=440 --with-fp" .
I'm using an updated CRUX PPC 2.7 (32bit): gcc-4.5.3, binutils-2.21.1,
glibc-2.12.2
cheers,
